National Solar Radiation Database (NSRDB)

The National Solar Radiation Database (NSRDB) is an extensive collection of solar radiation data used by solar planners and designers, building architects and engineers, renewable energy analysts, and experts in many other disciplines and professions. 

Current Version

In 2012, the NSRDB was updated to include data from 1991 through 2010. The 1991–2010 database builds on the 1991–2005 version, and contains data for over 1,400 stations across the United States. The NSRDB offers hourly solar radiation data including global, direct, and diffuse radiation data, as well as meteorological data for stations from the NCEI Integrated Surface Database (ISD).

Partnerships

NCEI collaborated with the following organizations to develop the NSRDB:

  • Department of Energy (DOE) National Renewable Energy Laboratory (NREL)
  • National Aeronautics and Space Administration (NASA),
  • Northeast Regional Climate Center
